So I recently bought the MSI 1080Ti Sea Hawk and currently have my old 980Ti and don't have any plans on selling it. I currently do YouTube and render most of my videos in 2K or 4K. My question is can I run both to render videos to shorten render times etc. I have no intention of trying SLI as I know I can't use 2 different models. My second question is can I use the 1080Ti to run games and the 980Ti to record with OBS etc? Sorry if I sound stupid. Thanks in advance.

Running mining uses each card separately, no need to try to grab the framebuffer from one card, send it along the PCI-E bus, and transcode on the other card. Running live , NVENC would allow you to hardware encode on the same GPU with little/no loss in performance. The 980ti would be a dedicated phys-x card under that scenario, but little else. ( Unless you are running a game that specifically supports explicit multi-GPU mode under DirectX 12) This assumes of course the power needs are met for being able to run both cards.

My Mobo has multiple GPU slots I can fit 2 GPU's on it so I don't see why it wouldn't work. Unless it's a software restraint.

So how would one setup the 980Ti as a physX card? Would it require a SLI bridge or is it a plug and play situation?
